Frequently Asked Questions
When I turn on the robot, it has no response. Why?
1. Low voltage, please recharge or replace batteries. 2. Batteries installed in wrong polarity (+/-). 3. Incorrect wiring on battery holder or motor.
When I control the robot to move forward, it moves backwards. How can I fix this?
The wiring of the motor is connected in reverse. Please reconnect the wiring to correct the direction.
How do I program my robot or restore factory settings?
Download the official coding software, connect the robot via USB, select the correct COM port and board type. Use "Restore Firmware" to resume factory settings or "Online Firmware" for live testing.
I cannot connect the robot to the computer. What should I do?
This usually means the driver isn't installed. Please install the driver from the "Help" menu in the software, restart the robot, and try connecting again.
Why doesn't the robot move with only a USB power supply?
USB power only supports the chip and sensors. To drive motors or servos, you must connect batteries and switch on the main power button.
Why doesn't the Line-following Sensor work correctly?
Ensure the distance to the map is 1-2cm. Avoid strong light interference and ensure your map is made of non-reflective material.
